The MPIS servers are too costly and under power, and the Itanic servers are going to sink.

The only interesting technology is XFS/CXFS, but let's not forget that it was an SGI developer who copied code from the original Unix source to the Linux kernel, and SCO showed that piece of code in the US court.
